iOS: Onavo Count, our favorite data usage tracker for Android, is now available for iPhone users looking to avoid hefty overage fees from carriers who are all too eager to add them to your bill.

The app works much like its Android cousin. You can give Onavo Count your billing cycle end date, and the app will keep an eye on your data usage over the course of the month and show you which apps are using the most data and when, so you can see which apps are talkative when you're not using them. Onavo Count ranks your apps by data usage, and gives you an easy to understand chart so you can see who the biggest data hogs are, and whether you're in danger of hitting your bandwidth cap for the month.

Onavo Count also works seamlessly in combination with Onavo Extend, another iOS (and Android) app we love that compresses your mobile data to save you money on bandwidth. Both apps are free, and available now.
